Modular container

ABSTRACT

A modular container for the storage or display of articles, formed from a foldable unitary blank of sheet material. The container has a base panel, opposed first and second side panels and an end panel. A container-locating aperture is located adjacent the second side panel and is formed on the end panel, together with a tab-locating aperture that is located adjacent the first side panel. A container connecting tab projects from the first side panel, and may selectively be folded to locate in the tab-locating aperture, or to locate in the container-locating aperture of another container and thereby connecting the containers together in side-by-side relationship.

BACKGROUND TO THE INVENTION

[0001] THIS invention relates to a modular container for the storage or display of articles.

[0002] Numerous containers that are folded and erected from blanks of sheet material are known. Many of these containers may be collapsed when not required and stored as flat sheets, ready to be re-erected when needed. Some of the containers of this type may be connected to one another in side-by-side relationship or in a stackable orientation. Many containers that are arranged in this manner have tabs projecting from the walls of the container, which may be glued to another identical container. Once glued these containers are not easily separated without damage being inflicted to the container walls. Accordingly, it is difficult to repeatedly erect and collapse such containers after they have been joined to other containers.

[0003] Certain containers known to the art incorporate engagement tabs which pass through co-operating slots of another like container, or several containers are arranged in an overlapping relationship. However, such arrangements do not provide adequate coupling of the containers and containers that are joined together in this manner are typically prone to separation. Alternative means for connecting containers are known to the art, whereby co-operating connecting tabs may be inter-linked to connect containers together, but such linkage formations are not particularly strong and may be damaged easily with repeated use.

DESCRIPTION OF AN EMBODIMENT

[0051] A modular container 10 according to the invention is depicted in FIG. 4. The container is formed from a unitary blank 12 of corrugated polymeric sheet material. The container is intended for the convenient storage or display of articles, and may easily be erected to form a single container, or may simply be adapted to be joined to other like containers. The containers joined in this manner may easily be separated again to form single containers, or may be collapsed back into flattened blanks for convenient storage.

[0052]FIGS. 1 and 2 show the blank 12 which has a base panel 14, and opposed first and second side panels 16 and 18 extending from the sides of the base panel. When folded into a vertical orientation, the first and second side panels form the side walls of the container. On the side panels are provided respective first and second end panel portions 20 and 22 which are foldable from the first and second side panels respectively. The first end panel portion has a projecting tab 24, which is engageable with a corresponding aperture 26 formed in the second end panel portion. When the projecting tab of the first end panel portion is engaged in the aperture of the second end panel portion, the end panel of the container is assembled, the end panel being shown generally as reference numeral 28 in FIG. 3.

[0053] Located on the other ends of the first and second side panels 16 and 18 are provided first and second front panel portions 30 and 32, the first front panel portion having a projecting tab 34 which is engageable within an aperture 36 formed in the second front panel portion. When so engaged, the first and second front panel portions form the front panel, shown generally as reference numeral 38 in FIG. 3.

[0054] An end container connecting tab 40 is partially cut out of the first end panel portion 20. The fold between the first side panel 16 and the first end panel portion forms a hinge 42 for the end container connecting tab, enabling the end container connecting tab to be positioned in a tab-locating aperture 44 or folded out therefrom. Similarly, there is a front container connecting tab 46 formed out of a front tab-locating aperture 48 in the first front panel portion 30. The front container connecting tab may also be positioned in or out of the front tab-locating aperture.

[0055] Extending from the base panel 14, there is provided an end reinforcing panel, shown generally as reference numeral 50, which comprises an end outer panel portion 52 and an end inner panel portion 54. There is a corresponding front reinforcing panel, shown generally as reference numeral 56, which comprises a front outer panel portion 58 and a front inner panel portion 60.

[0056]FIG. 3 clearly shows the end and front panels 28 and 38 in assembled configuration, with the projecting tabs 24 and 34 engaged in the corresponding apertures 26 and 36. The end reinforcing panel 50 is then folded from the base panel 14, such that the end outer panel portion 52 abuts the end panel. The end inner panel portion 54 is then folded over the end panel, thereby enveloping the end panel together with the engaged projecting tab and aperture 24, 26. A projecting tongue 62 is provided on the end inner panel portion, which is positioned in a complemental slot 64 cut out of the base panel. Similarly, the front reinforcing panel 56 is folded over the front panel to envelop it, and a projecting tongue 66 engages a complemental slot 68 provided on the base panel.

[0057] When a single modular container 10 is required, the end container connecting tab 40 is positioned within the tab-locating aperture 44. The engaged tab and aperture is then enveloped within the end outer and inner panel portions 52 and 54. Accordingly, in this configuration there are no tabs projecting from the modular container and no slots or apertures are visible when the container is erected, as is depicted in FIG. 4.

[0058] Should it be desired that a second container 10 be connected to the first container then, prior to the end and front reinforcing panels 50 and 56 being folded over the end and front panels 28 and 38, the end container connecting tab 40 of the first container is folded out externally from the tab-locating aperture 44 to project from the first side panel 16. The second end panel portion 22 of each container is provided with a container-locating aperture 70, formed adjacent to the second side panel 18. The size and shape of the container-locating aperture is configured to be identical and complemental to the tab-locating aperture 44 formed on the first end panel portion 20.

[0059] Prior to the end and front reinforcement panels 50 and 56 being folded over the end and front panels 28 and 38, the end container connecting tab 40 of the first container is positioned into the container-locating aperture 70 of the second container. This is clearly illustrated in FIG. 5. When the end container connecting tab is engaged in the container-locating aperture, the end reinforcing panel may be folded over the end panel into the assembled position. If a further container had been required, the end container connecting tab 40 of the second container would have been folded out from the corresponding tab-locating aperture 44 to project away from the second container prior to the end reinforcing panel being placed in position.

[0060] The front container connecting tab 46 may be connected in a similar fashion to a front container-locating aperture 72 formed on the front panel portion 32. The front reinforcing panel 56 could then be folded into the assembled configuration in a similar manner to that described in relation to the end reinforcing panel.

[0061] In this manner it is possible to cover all of the interconnecting tab and aperture formations formed on the blanks 12, whether they are connected to form a single modular container 10 or a plurality of containers connected in side-by-side relationship.

[0062] As can be seen from the drawings, it is preferred that the front panel 38 of the container 10 is of a lesser height than the end panel 28. This enables greater accessibility and visibility into the container.

[0063] In a preferred embodiment of the invention, as depicted in FIG. 4, partitions 74 and 76, having co-operating alignment slots 78 and 80, are positioned within the container 10 to form compartments therein. Numerous projections 82 extend from the partitions and having chamfered edges 84 to facilitate location within co-operating panel slots 86 formed in the walls of the container. This enables convenient separation of articles within the container or, alternatively, provides support for tall items arranged in the container.

[0064] The first and second side panels 16 and 18 may have chamfered or shaped edges 88, to account for the reduced height of the front panels 38 relative to the back panel 28. The partition 76 may also be shaped accordingly.

[0065] A flap 90 may be cut from any one of the front or end reinforcement panel portions to enable a card or label to be inserted in the flap. This would be particularly suitable for identifying articles contained in the container or for advertising or promotional material which may be used in relation to the articles.

[0066] There are various alternative embodiments of the container which are possible and that fall within the scope of the invention. Furthermore, the containers may be formed from blanks of a sheet material that are manufactured from card, cardboard, polymeric sheets, corrugated boards or other similar materials. Polymeric sheets are particularly useful as they may be easily cleaned with a cloth and reused.

[0067] The main advantage of the invention is that containers may easily be connected securely to one another in a side-by-side configuration. In addition, if desired, the containers may be again released from one another and collapsed to form flat blanks enabling convenient storage of the containers when not required. Any number of containers may be connected together making the container suitable for applications on shelving, and especially for the storage of small items such as nuts and bolts in a workshop, or for the display of articles in shops. Due to the reinforcing panels, at the front and end of the containers, and the double wall sections between connected containers, the arrangement is particularly resilient and rigid.

[0068] It should be appreciated that the containers described in relation to the present invention may have more that two side panels and may accordingly be polygonal in shape. This enables the containers to be joined in side-by-side relationship to form circles. Accordingly, the phrase “opposed” in the claims should be understood in this manner, and not should not be interpreted to limit the containers to only two side walls, arranged in a substantially parallel configuration.
